Abstract: Round-off error in fixed-point arithmetic is minimized by changing the magnitudes of two multipliers simultaneously. The dynamic range of an intermediate output is thus maximized to increase computation precision. A much smaller round-off error, caused by fixed-point arithmetic, thus results.

Abstract translation: 通过同时改变两个乘法器的幅度来最小化定点运算中的舍入误差。 因此，中间输出的动态范围被最大化以增加计算精度。 因此，由定点算术引起的更小的舍入误差就会导致。

Abstract: The ability to remove a watermark from an encoded image opens the possibility of various novel applications. Several such applications are detailed. One employs a reversible watermark in conjunction with a second (robust) watermark. In this arrangement, the payload of the reversible watermark conveys information about the robust watermark (e.g., encoding parameters, or an error signal), permitting removal of the robust watermark from an uncorrupted encoded image. By such arrangements, the encoded image can be fully restored to its pristine, unencoded state even if several different watermarks have been applied.

Abstract translation: 从编码图像中去除水印的能力打开了各种新颖应用的可能性。 几个这样的应用程序是详细的。 一个结合第二（鲁棒）水印采用可逆水印。 在这种布置中，可逆水印的有效载荷传达关于鲁棒水印的信息（例如，编码参数或误差信号），允许从未损坏的编码图像中去除鲁棒水印。 通过这样的布置，即使已经应用了几个不同的水印，编码图像也可以完全恢复到其原始的未编码状态。
